August 23, 2024 – HDPE impermeable membrane, a plastic impermeable material that emerged in 1969, was introduced to China only in 1980. Since then, it has gradually gained widespread application. In particular, the “impermeable membrane” incident at the bottom of the Old Summer Palace lake in 2005 sparked unprecedented public attention to urban ecology, highlighting the growing importance of HDPE impermeable membrane in the field of environmental protection. Nowadays, this material has become a common material for environmental protection in China, and the developed cities in East China have even become the main production bases for HDPE membranes.
According to the Color Masterbatch Industry Network, HDPE impermeable membranes play a crucial role in various projects due to their excellent impermeability and multiple advantages. Their high impermeability coefficient is attributed to their strong tensile mechanical properties and excellent elasticity, allowing them to adapt to the expansion or contraction of the base surface and effectively overcome uneven settlement. Additionally, the material exhibits superior chemical stability, resisting corrosion from various strong acids and alkalis, making it widely used in sewage treatment, chemical reaction tanks, and landfills.
Furthermore, HDPE impermeable membranes demonstrate remarkable aging resistance, with strong anti-aging, UV resistance, and decomposition resistance, enabling their exposed use with a material lifespan of 50-70 years. They also possess excellent puncture resistance, withstanding most plant roots, giving them a significant advantage in environmental protection and landscaping applications.
It’s worth mentioning that HDPE impermeable membranes not only offer excellent performance but also provide cost-effectiveness. By adopting new technologies to enhance impermeability, the production process has become more scientific and efficient, reducing product costs compared to traditional waterproof materials. In practical engineering projects, using HDPE impermeable membranes can save approximately 50% of costs.
In terms of construction, the high flexibility of HDPE impermeable membranes allows them to meet the impermeability requirements of different projects. Utilizing hot-melt welding, the seams exhibit high strength, facilitating convenient and rapid construction. Moreover, the material is environmentally friendly and non-toxic, employing non-toxic and environmentally friendly components. The impermeability principle involves ordinary physical changes without generating harmful substances, making it an optimal choice for environmental protection, aquaculture, and drinking water reservoirs.
HDPE impermeable membranes find widespread applications in various fields, including environmental protection, sanitation, water conservancy, municipal engineering, landscaping, petrochemicals, mining, transportation facilities, agriculture, and aquaculture. Their outstanding performance and broad applicability make HDPE impermeable membranes an indispensable material in the current environmental protection field.
